来自3PI有效Action的领先阶QED电导率

Leading Order QED Electrical Conductivity from the 3PI Effective Action

M. E. Carrington, E. Kovalchuk

摘要:

本文利用3PI有效作用量研究了QED中的电导率。我们的工作是在有效的行动中以3圈为序。我们表明,所得到的电导率的表达式是明确的规范不变的,并恢复捏和共线贡献的积分方程自然产生的形式主义。包括所有前导阶项,而不需要任何种类的功率计数参数。

英文摘要:

In this article we study the electrical conductivity in QED using the resummed 3PI effective action. We work to 3-loop order in the effective action. We show that the resulting expression for the conductivity is explicitly gauge invariant, and that the integral equations that resum the pinching and colinear contributions are produced naturally by the formalism. All leading order terms are included, without the need for any kind of power counting arguments.
